摘要
Intracoronary stents were implanted in 61 patients(58 males and 3females,aged 52.1±8.3 years) with coronary heart disease in thishospital from June 1995 to May 1998.Seventy-two intracoronary stents (12Palmaz-Schatz.8 OR-I,45 Multilink,6 NIR and 1 Wiktor-i) were implanted,45 in LAD(62.5% ),22 in RCA(30.6%) and 5 in LCX(6.9%),Indications forstenting included 30 de novo(41.6%).4 bail-out(5.6%)and 38 Suboptimal(52.8%)stenting.The procedure success rate was 100%.Averagediameterstenosis decreased from 75-100% to -10-10% after stenting.There was one death from subacute stent thrombosis Two cases hadhematoma at the pancture site.There were no complication of acutethrombosis,cerebral hemorrhage and emergency CABG.During 1-36 monthsfollow-up,6 cases had relapse of chest pain,incinding 4 case ofrestenosis proved by argiography.Coronary stenting is a successfulmeans for atent"stand-by" and bail-out procedure for balloon angioplasty.Optimal angiographic results can be achieved in the majority ofpatients by proper stent sizing and deployment techniques.Anticoagulation should be given according to the characteristics oflesions and post-stenting angiographic findings so as to reducevascular and bleeding complications as well as hospital stay followingcoronary angioplasty.The results suggest that intracoronary stentinghas high success rate and low restenosis rate.It is an effective andsafe interventional therapy for acute coronary closure or selected denovo complex lesions following PTCA.
